Specific implementation mode
Embodiments of the present invention are described below in detail, the example of the embodiment is shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the present invention, and is not construed as limiting the claims.
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings：
Technical solution disclosed in this invention includes that position range region takes the method for weight, irregular overlapping region displaying skill
Art and method and flow in map inquiry personnel's key index information.
I, the method for taking overlapping region based on multiple position range regions：
Graphical information is built by geography information, if putting latitude and longitude coordinates and coverage area centered on geography information, according to
Latitude calculates the reduced unit of longitude and length unit, and the unit of unified hub point and coverage area builds border circular areas later.
If geography information is the latitude and longitude coordinates on two vertex, calculated in addition according to the latitude and longitude coordinates on known two vertex
The latitude and longitude coordinates on two vertex, it is unified that longitude and latitude is converted into length unit, rectangular area is built later.If it is known that multiple
The longitude and latitude of point after then carrying out Conversion of measurement unit, connects multiple point structure polygonal regions.Multiple figures are calculated by mathematical method
Intersection, you can obtain overlapping region.
II, it is based on irregular overlapping region map display technique：
The figure that calculated figure is converted to set representations, by between a certain number of boundary points and boundary point
Line constitutes the irregular overlapping region of closure, and figure point set is then converted to spatial geography data, is illustrated in map.
The method and flow of III, map inquiry personnel's key index information：
National administrative division boundary library is established, personnel's key message is segmented, establishes participle index.In reseaching staff
When information, personnel are filtered according to whether in the bounds of search first, are then matched, then according to retrieval
The full word matching of information, searches for generally, returns to search result, and be shown.
The method flow of the present invention is discussed in detail with reference to specific embodiment.
First, geography information classification and regular figure structure are carried out：
(1) central point known to and coverage area, are classified as circle, as shown in Figure 1, building circle according to A points and radius
Domain.
(2) known that rectangle is classified as to angular vertex, as shown in Fig. 2, calculating two points of C, D according to the transverse and longitudinal coordinate of A, B point
Coordinate, then connect ACBD build rectangular area.
(3) multiple vertex, are classified as polygon known to, as shown in figure 3, being sequentially connected each vertex structure polygon area
Domain.
Then, region overlapping calculation is carried out：
As the sample calculation of one embodiment, as shown in Figure 4：A, B is regional export, and E is the central point of this person, is passed through
Build rectangle and border circular areas, calculate overlapping region can more accurate show staff zone of action, and personnel can be estimated
It may be from the outlets B.
As the sample calculation of another embodiment, as shown in Figure 5：A, B, C obtain the zone of action of same personnel simultaneously,
So by building multiple zone of action, calculating overlapping region can more accurate show staff zone of action.
Preferably, figure transfer point set representations are carried out：
As shown in fig. 6, the point centered on geometric center, the point that ray intersects with figure is taken according to certain angle, composition
Point set is result.
The whole implementation step schematic diagram of the present invention is as shown in fig. 7, specific steps include：
step1：Obtain the position data of same personnel same time.
Can be by the matching degree of personnel's attribute information, it is same that acquisition time of geography information etc. obtains same personnel
The position data of time.Data information is more accurate comprehensively, and final result of calculation is more accurate.
step2:The geography information in data is extracted, and carries out classification processing.
According to the geographical information classification for obtaining data, matching meets the parameter of structure figures shape, priority match regular figure.
step3：After carrying out Conversion of measurement unit to geography information, corresponding figure is built.
Geography information Conversion of measurement unit is carried out to need to judge the geographic coordinate system and place longitude and latitude that original geography information uses
Then information calculates the correspondence between the length unit of current location and longitude and latitude, realize Conversion of measurement unit.
step4：Figure intersection is calculated, overlapping region is obtained.
When multiple regions calculate, the intersection of first figure and other figures is calculated successively, deletes other regions, it is final to protect
The region stayed is overlapping region.
step5:Graph data is converted into point set data.
When figure is converted to point set data, a fixed angle (such as 1 degree) is taken by vertex of the geometric center of figure
The intersection point (it is convex graphical to calculate figure, and intersection point is not in multiple) of two rays, recording ray and figure, with such
It pushes away, calculates all point sets.
step6:Point set data are converted into spatial geography data.
Length unit is converted to the longitude and latitude letter for meeting this coordinate system by the coordinate system of the specified spatial geography data needed
Breath.
step7:The accurate zone of action in show staff's certain time period in map.
Point set data comprising longitude and latitude information are connected in sequence, and are illustrated in map.
The disclosed calculated overlapping positions information of method through the invention, can accurately position someone, and
It supports to show in map.Solves huge mixed and disorderly in the display technique of existing position range region, the problem of user experience difference.
Entire work flow can be independently operated, without carrying out performing creative labour again and groping research experiment.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be without departing from the purpose of the present invention
It makes a variety of changes.The above described is only a preferred embodiment of the present invention, not making limit in any form to the present invention
System, although the present invention has been disclosed as a preferred embodiment, however, it is not intended to limit the invention, any skill for being familiar with this profession
Art personnel, without departing from the scope of the present invention, when the technology contents using the disclosure above make it is a little change or
